massa To aZZfw/tomit mag/concern.' t i Be it known` that I, PETER GRABLER, a citil p Izenfof the United States, residing at Cleve l land, in the county ofCuyahoga and State' i.; "offQhio,`have invented new and` useful Im- `proveinen'ts in Casters, of whichthe follow iis a specification. t

1j `yThis*inveention is `an improved caster oi wtheltype usually employed for "supporting, and facilitating the moving of movable articles, suchas furniture-sliding doors and t any particular or specilicclass of such mov- *yablearticles i i y y `-`i` One of theobjectsofthe invention is to `provide a caster, constructed to permit n .attachmentfto the article which it is inv .tended to support, in suchmanner that all l l f of the working parts are concealed, `except y `soinuch ofithe supporting roller, as is "afnecessary toraisevsaid articleclear of the ,urface` from which ,it is supported.`

compartment being usually made up of slidable doors or sections, which may be moved to one side, to permit access to the articles within the case. In order that 4the articles on display may be protected from dust, and the like, it is desirable, and in fact important, thata substantially close contact be maintained between the edges of thedoor and the surfaces with which they co-` operate. kThe present invention is designed to meet'these requirements, and in the drawings is illustrated as attached to a door of` the character above specified, but its use is jthel lower edge thereof."

said .rail is1 a recess 12 ,provided with an y t screws 16, 17, said plate being provided with "mit Aajswiveling'ff movement of the "roller, Whenthe a t ticle; is moved, without affecting an inwardly extended locking pin 18.

The caster comprises a forked caster memswivel 22 to yan adjusting member 23, the pin or swivel 22 being of sufficient length :to permit of the 'insertion of' antiiriction balls 24 between the supporting member and the caster member. The supporting member is provided with external screw threads 25, `designed to mesh with corresponding threads `26` upon the interior of a tubular casing 27, and located near the upper open end of 4said casing. The supporting member' is provided with an annular flange 28 provided with notches 29 which are shaped to be engaged by the locling pin 18. The

lower edge of the casing 27 is provided with flanges or ears 30, designed to rest against the lower edge of the rail 10, screws 31, or

.other attaching means, being employed to secure the casing to said rail.k When the caster is used upon-a door as abovel described, it may, under some conditions, be desirable to have the roller 21 run in a track. A U-shaped track 32, preferablyv of channel iron is illustrated in the drawings.`
